Introduction In organic chemistry the substitution reactions is the most important reactions especially Nucleophilic aromatic substitution reactions where nucleophile attacks positive charge or partially positive charge As it does so it replaces a weaker nucleophile which then becomes a leaving group. They have different mechanisms which means their ability to occur is determined by factors like sterics around the alkyl halide the choice of nucleophile used or even the solvent for the reaction.
